Re: Sarah's appearance in general
I, too, was surprised by the new hairstyle. To me, it seems out of character. It's not trendy. And Sarah should be trendy!
But then, I remembered that when I first became a mom, I decided that I needed a "mom hairstyle" (wash-n-go/no-fuss). So then I thought, well, maybe now that Sarah's a mom, she decided that she needed a mom hairstyle too. At least, that is how I am justifying it to myself. :) Plus, if you spend a lot of time chasing aliens, you probably don't always have time to do the whole blow-drying-with-product-and-a-round-brush thing.
Eventually, I came to my senses and grew my "mom hairstyle" back out into long layers. Maybe Sarah will too. :)
